the old bearings should have a number stamped on the side of it, but if not someone that knows that kart will chime in 206 is small 207 is large I believe is rightanother newbie question. We were putting the axel back on the kart last night and realized the axel bearings need to be replaced. Axel bearings come in small and large. Which bearing size would I need to order? 2011 Millennium Impulse, 32 inch rear axel...can provide more info if needed to help. Everybody on the forum has been super helpful and nice and I appreciate anybody who takes the time to help me out!
We made sure to measure everything out before taking it apart. Do you have any other information related to track widths that would be helpful to a newbie?The location of the rear hubs are more important than axle length. Make sure you set your track width back where it was.
